Indium Recovery from Waste Liquid Crystal Display via

As such, the influences of SiO 2, Al 2 O 3 and Fe 2 O 3, contained in LCDs, can be ignored or avoided, and only CaO, K 2 O and Na 2 O would consume partial pressure of HCl gas, reducing the indium recovery reaction rate. The present study might provide important inspiration for indium recovery from waste LCDs via chloride volatilization process.

New technique developed to recycle indium from waste LCD

The highest indium recovery (99.8%) using an acid solution with a pH of 2 was achieved when a relatively high concentration of zinc was used (100 grams per litre, g/L). Overall, the best results for indium recovery were found using a solution with an acidity of pH 3, which led to high recovery of indium even at low concentrations (5 g/L) of zinc.
